DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 398,439, dated February 26, 1889.

Application filed October 17, 1888- Serial No. 288,315. (No model.)

To all whom it may (OH-(3677b:

Be it known that I, FRANK PARSONS, a citizen of the United States, residing at Russell Springs, in the county of Logan and State of Kansas, have invented certain new and useful Improvements in Door-Holders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improved door checks and holders.

It consists in a spring-bar having thereon a latch or holder and a yielding stop or check, as will hereinafter be fully explained.

In the drawings, Figure 1 shows the check made of a piece of a flat bar. Fig. 2 is the same made of a round bar. Fig. 3 is a staple used to limit the upward movement of the spring-bar. Fig. 4 shows the anti-friction staple driven into the under edge of the door. Fig. 5 is a modification.

The check-bar is preferably made of a single bar or piece of metal, a, bent in the form shown. I, however, do not limit myself to the use of metal in the manufacture of the check. It maybe made of a wooden. bar bent into proper form by any of the well-known pr0- eesses, or .it can be made in several pieces. Some may be made of wood and the others of metal, the several pieces being united by rivets or other suitable fastenings to give the form shown in the drawings. I prefer to make the check of a single bar, whether of wood or iron, and bend it into the proper form.

In constructing my device I take the single bar a, and by suitable mechanism form the perforated shank a, by which the check is made fast to the wall by means of. screws or otherretainingmeans. Instead of screw-fastenings, one or more small staples could be driven into the wall, so 'as to form a socket into which the shank a could be slipped or from which the check could be lifted when desired.

Near the middle of the bar I form the checkloop a by bending the bar upward, as shown.

rial.

This (fliQCk-IUOI) is elastic and yields slightly to pressure. On the outer end of the bar I form the catch (1 inclined on its outer side, as shown, so that the door will slide readily upon it. Space is left between the catch and the check-loop suiiiciently wide to receive the door.

The inner arm, a, of the latch a has its lower end detached from the shank of the check at oi so that the said arm a may yield outwardly, in order to admit doors of different thicknesses between the latch and the checkloop. This may be accomplished by providing the lower end of the arm a with the eye embracing the shank-check, as will be understood from Fig. 1, or the said arm may be simply lapped alongside the shank of the check, as seen in Fig. 2.

A padding of rubberor other suitable ma teriahb, is fixed on the bar in the door-space, V

the purpose of which is to deaden all noise and to relieve the shock given by the door when the latter is forcibly thrown into check.

I employ a'staple, c, to limit the upward spring or movement of the bar. Its purpose is to prevent injury to the check-bar when the latter is released after having been depressed to unfasten the door (I. The staple is placed over the flexible arm or portion, a", and driven into the floor, as shown.

A small anti-friction bar, d, placed on the under edge of the door it in such position as to provide the hearing which presses on the catch. It prevents wear on the door and obviates friction.

I In practice a check made with its arm a flexible and the other parts inflexible would give excellent results. I make the check with the arm a flexible and the check-loop (i also flexible, as herein described. The packing b deadens sound and protects the loop a by supplying additional yielding stopping matc- This packing, it will be seen, is also supplied against the face of the inner arm, a, of the latch a", and serves as a frictionbearing for the front edge of the door. This friction bearing or surface binds against the edge of the door and prevents same from being released from latch a by the reaction or return of the door after the latter has been swung forcibly open into engagement with having its arm a flexible, and the check a r and the latch a could be secured to the outer end thereof in proper position, as shown.

In Fig. '5 I show a stop having primary loop a and a secondary loop, a by which I gain greater elasticity of the bar. The secondary loop, a serves a double purpose: First, it

provides elasticity similar to and of the same character as that afforded by the primary loop or check, a secondly, it gives greater strength to the flexible arm, whereby a better action of the stop is secured. I employ, preferably,

only one secondary loop, though two or more could be used. In using the secondary loop a the flexible arm of the primary loop could be dispensed with and it could be made rigid or Without flexibility, as hereinbefore described. The inner arm, a, of the latch is loosely connected With the shank of the check to permit the latch to yield vertically, so that the door may ride over the latch in the event of the distance between the lower end of the door and the floor being less than the distance of the height of the said latch.

Having thus described my invention, What I claim, and desireto secure by Letters Patent, 1s-

The herein-described door-check, composed of the elastic arm a the check-loop a and the latch a having its inner arm, a, movable on the shank of the check, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two Witnesses.

FRANK PARSONS.
